[0002] A large amount of construction dust is generated during the construction of a building, which mainly includes silica powder and non-mineral powder; silica is present in common building materials, including cement, concrete and mortar. Once the material undergoes significant changes, such as cutting, drilling, grinding and sandblasting materials such as granite, sand and sandstone, silica dust, also known as respirable crystalline silica, is generated. This is the most dangerous construction dust. Fine dust particles are dangerous, especially silica dust particles. After inhalation, dust can reduce lung capacity, increase overall pressure on the heart, and cause various diseases; it can also irritate the eyes, nose, throat, skin and lungs. In order to protect the health of workers and prevent construction dust from spreading to the city and causing secondary pollution, it is necessary to control the dust at the construction site.
